i This invention relates to new and useful improvements in a bottle closure.

The invention has for an object the provision of a device of the class mentionedcluding a\bottle neck cap having na. large base portion with a small upper threaded portion and a conical top formed with a pin-hole aperture, a cover for engagement on said'capv formed with a large base engageable on said large base portion and an interior Vsmall threaded top engageable on said small upper threaded portion, and a sealing-member supportedin said cover for engagement, against said conical cap topand against the pinhole 2 aperture for preventing evaporation of contained iiuid. 1

The invention also proposes a means for Aadjusting the sealing fmember to close the pinhole aperture in the cap member when .2 ther cover is placed loosely upon the cap and not screwed in place. l

For further comprehension of the invention, and of the objects and advantages there'.-

of, reference will be had tothe following description and accompanying drawing, and to the appended claims in which the various.

novel features of the invention are more particularly set forth.

The bottle closurecomprises a bottle Vneck cap 10 having a large Jbase portion 11 with -der the action of a die. within the-conical top 13 is locatedat its 90 i930.l semi Nb. 457,156.

a small upper threaded portion 12 and a conical top13 formed with a pinhole aperture 14,

a cover 15 for engagement on said cap 10 and formed with a large base portion 16 forl engagement i'ipon the base portion 11 of the 55 ca'p and an interior small threaded portion 17 for engagement upon the threaded portio`n 12, and a` sealing member 18 supported in said cover 15 for engagement against said conical cap top 13 and againstthe inhole ,60 i

14 for preventing evaporation of .t e conltained liquid.

The bottle closure is shown upon a bottle 1 9 of any design or construction. It is particularly intended that this bottle holdper- 05 e or any volatile liquid. The neck 20 -o/f the bottle isy formed with ,threads engageable withthreads 21 formed in the large base port-ion 11. The cap 10 should preferably be made from sheet metal and hi hly polished for aiding to its appearance. Tie lower edge 22 isshown turned up so as to form a finished edge in the cap. A rim portion 23 is formed v directly above the threads 21 and is providedy with the threadedportion 12. A washer 25 is positioned within the cap 10 and rests 80 against the inside of the curved portion 24 and is engageable against the to of the neck 20 of the bottle as -shown in ig. 5. This forms a tight connection to prevent leakage` from the interior of the bottle and theinw ner sides of the threads 21. The conical top 13 is vintegral with the top of the threads 12 and may be formed by spinning or drawn iin- The lpinholel 14 center and is of small diameter so that but small quantities of the contained liquid may be discharged from the bottle at a time.

The cover 15 is made from sheet brass by spinning or stamping and is shown lto consist v of two sections, namely an outer section 26 and an inner section 27. The bottom edge 28 lof 'the outer section is fiared as clearly shown in Fig. 2 and the bottom edge of the inner section lis .turned upward around the '10 flared edge 28 and clamped in place for firmly securing both sections togethers 'The outer section 26 consists of a cylindrical portion 29 terminating at the bottom in said flared portion 28 and connecting at the top with an enlarged hollow head 30, which is .slight` ly convexed at the top 31: A projection 32 extends downwards from the central portion of the top side of the head 31 and slightly bows down the sealing member 18 as may be observed in Fig. 2. It is calculated that When the cover is engaged upon the cap, the bcwed down portion of the sealing member is tightly pressed into the pinhole 14. The inner section 28 is arranged coaxially within the section 29 and consists of a 'cylindrical portion 33 connected with the said upturned edge which encircles the iiared edge 28 of the outer section, and connects with a reducer central portion 28 which in turn connects with the said threaded portion 17. A hollow space 34 is thus provided between the sec-1 tions causing the cover to bequite light. The

topkof the threaded portion 17 is opened and is slightly dug into the sealing member 18 so as to retain the sealing member against free motion within the cover. The sealing member is arranged flat against the inside of the top portion 31 of the cover and between the top edge of the threaded portion 17 of they inner section. This sealing member may be of cork, rubber and the like.

p In Fig. 7 a means has been provided for ad- .justing the sealingmember to closetheapinhole and the cap member when the cover is *placed loosely'upon the cap and notscrewed yin place. This means comprises a iexible seal- -ing member 18 engaged over the open top4k of the threaded portion 17 and secured upon the exterior of thethreaded portion 1-7 by a wire 35 -ormed in a circle andhaving its ends twisted together. A spring 36 is `at tached upon the bottom of the top portion 31 end 37 capable `of being attened out. The normal position of the spring is that shown in r Fig. 7 in which the curved front end 37 forces the Psealing member `18 downwards so that it may engage against the pinhole 14 even though the cover is not screwed in place on the cap. When the cover is screwed down in place thje spring 37 lattens out to allow such screwing. l The operation of the device may be nnderstood by first assuming it in the condition as shown in Fig. 4, that is, with the cover tightly screwed in place upon the cap. In this condition the sealing member acts against the pinhole 14 so as to prevent the leakage of fumes or liquid from the interior of the container tothe atmosphere. The 'threads v17, engaging u on the threads 12 form an air packing an this air packing is supplemented by thecylindrical portion 27 of the outer section 26 and has a'curved front of the innersectionv of the cover engaging,.-

When the cover is removed the liquid from within the container may 'be discharged through thepinhole by shaking. If the cover is loosely placed upon the cap of the bottle without screwing it down, there is a certain amount of sealing produced in that the overhanging sides 27 engage against the outsides of the threads 11 forming an air packing as before explained. In addition, the top of the thread portion 12 engages against the bottom of the threads 17 producing some sealing effect, finally the thirdgsealing` effectis obtained at the 'la'red edges 28 which engages -the bottle 19 after the cover is turned into- Vhile I have shown and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is 1.
